# Periodic and quasi-periodic attractors for the spin-orbit evolution of Mercury with a realistic tidal torque

@article{Bartuccelli2017PeriodicAQ, title={Periodic and quasi-periodic attractors for the spin-orbit evolution of Mercury with a realistic tidal torque}, author={Michele V. Bartuccelli and Jonathan H. B. Deane and Guido Gentile}, journal={Monthly Notices of the Royal Astronomical Society}, year={2017}, volume={469}, pages={127-150} }

In this paper, we make a detailed study of the spin-orbit dynamics of Mercury, as predicted by the realistic model which has been recently introduced in a series of papers mainly by Efroimsky and Makarov. We present numerical and analytical results concerning the nature of the librations of Mercury’s spin in the 3:2 resonance. The results provide evidence that the librations are quasi-periodic in time, consisting of a slow oscillation, with an amplitude of order of arcminutes, superimposed on…
